To all whom it may concern:

Be it known that I, ALBERT H. LEWIS,

citizen of the United States, residing at N ew Conierstown, in the county of Tuscarawas and State of Ohio, have invented new and useful Im rovements in Journal-Boxes, of which the ollowing is a specification.

My invention relates to journal boxes constructed with a view of lubricating shafts and axles; and its novelty, utility and ractical advantages will be fully understood rom the following description and claims when the same are read in connection with the accom anying drawin s, forming part of this specincation, in whic Figure 1 is a side elevation showing a shaft in proper position in my improved lubricat ing jouma box. Fig. 2 is a transverse see tion taken in the )lane indicated by the line 2-2 of Fig. 1, and showing the reservoir, the lubricant-conveyin bolt, the drum, the pressure roller, and the lBabbitt-metaI sections of my improvements. Fig. 3 is a transverse section taken in the plane of the line 3-3 of Fig. 1, looking in the direction of the arrow, and -showing one of the lubricant filtels of the improved -ournal box.. Fig. 4 is a cross-section on the line 4-4 of Fig. 1 to a show one of the lubricant retainersi. e., one

of the devices for preventing lubricant from workin out of the casing and for causing such lu bricant to pass from the shaft to the bottom of the casing. Fig. 5 is a detail side elevation showing such lubricant retainer roperly arran ed relative to the shaft. ig. 6 is a detail side elevation showing the arrangement of the sections of Babbitt metal relative to the shaft. Fig. 7 is a plan view showin the recesses in the longitudinal edges of the lower Babbitt metal section for the assage of the lubricant conveying belt. igs. 8 and 9 are views of one filter, removed. Fig. 10 is a detail section showing the relative arrangement of the casing, one filter and one door of the box.

Similar letters designate corresponding arts in all of the views of the drawings, reerring to which:

A is a shaft, and B is the casing of the journal box constituting the preferred embodiment of my present invention. The said casing B comprises a lower section a. and an upper section b, and these sections are arranged as illustrated, relative to the shaft A, and are hinged together at one side of the shaft, as indicated b, and are detachably connected to ether at the opposite side of.

the shaft, preferably through the medium of bolts-c extending through opposed apertured lugs d on the sections. The lower section a of the casing is providedat an intermediate point of its length with iLlCSQl'VOlI or well e 3 for lubricant; and it is also provided with bottom portions f which are inclined downward toward the reservoir 6, this in order to conduct excess lubricant to the reservoir in a manner that will be hereinafter set forth in detail. In one side of the lower, casing section a are formed openings 9 which are dis-- posed at opposite sir es of the resei voir e and are designed to be normally closed by doors h, arranged between and held in position b guides it". These doors h are shown as sli ing doors, but I would have it understood' that they may be swinging doors or doors of any other description without involving de parture from the scope of my invention, as claimed. The upper casing section b is provided with a dome i disposed above the reservoir e, as shown in Fi s. 1 and 2.

C is a drum journaled in suitable bearings in the reservoir 6 and provided by preference with end flanges as illustrated.

D is a belt,preferabiy of absorbent or pot-- ous material, passed around the shaft A and the drum 0 and having for its office to convey lubricant from the reservoir e to the said shaft, and E is a roller, preferably of rubber or analogous material, arranged above the belt D and having trunnions journaled and movable vertically in the dome 'i of the upper casing section, while F is a yoke carrying the said trunnions and adjustable up and down through the medium of screws G which bear in threaded apertures in the top of the dome i and are swiveled to the said yoke F. By turning the said screws G in one direction or the other, the pressure which the roller E exerts on the belt D to exress lubricant from said belt may obviously e increased or diminished at the pleasure of the party using my improvements. At this point it will be noted that by reason of the roller E hearing as stated against the belt D at a point above the shaft A, the said shaft when rotated will be profusely lubricated from the belt which is caused to travel by the shaft.

H H are lubricant retainers. These reshown in 4 an d 5, by reference to which it will be seen that they are curved in conformity to the sliaft'A and are provided with depending stems it. These depending stems k are disposed in sockets l rising from the bottom portionsf of the lower casing sec tion aand are mounted upon coiled springs m, the purpose of which is to yieldingly press the retainers against the shaft A with a view of increasing the efliciency of said retainers. Because of the provision of the retainers II it will be seen that any excess lubricant that may find its way to )oints adjacent to the ends of the casing, will be caused by the retainers to leave the shaft A and pass down to the bottom portions f of the lower casing section to the reservoir 8.

\Yith a view of filtering the used lubricant during its said passage back to the reservoir (2, I provide the filters I, one of which is shown in Figs. 8 and 9. The said filters I respectively comprise a U-shapcd portion preferably of sheet-metal, having rig it angle flanges I at its ends and also having openings 8 in its sides, and suitable absorbent material t, cotton packing or cloth forinstance, removably arranged in the said metallic section p. The said filters I are introduced through the openings 9 of the lower casing section a so that they rest crosswise of the casing and onthe bottom portions f of the lower casing section a, and so that their flanges r bear against the outside of said casing section a. Thus it will be seen that when the doors h are closed they will rest a ainst the flanges r and thereby hold the fi teis I in their proper working positions, while when the said doors h are opened, the operator may gras the flanges r and readily remove the filters from the casing B in order that the packing of said filters may be replaced with fresh packing or for any other urpose. It will also be apparent that beore the excess lubricant can find its way back to the reservoire it must pass through the openings 8 and percolate through the filtering material or packing i of the filters 1. From this itfollows that when it reaches the reservoir 2, the lubricant will be robbed of dirt and all other foreign substance collected during its passage over the shaft A, as is obviously desirable.

Removably arranged and held in the lower casing section (L is a section J of Babbitt metal or analogous material which is recessed at u to permit of the free passage of the belt D, and rcinovably arranged and held in the up er casing section b and arranged over the em portions of the Babbitt metal section J are Babbitt metal sections K. These latter and their arrangement relative to the shaft A and the section J are best shown in Fig. 6,- the sections K being spaced'in order not to interfere with the action of the roller E against the belt D.

During the rotation of the shaft A arranged in my novel journal box, it will be apparent that the belt D is caused to travel and convey lubricant from the reservoir 8 to the top of the shaft A. It will also be apparent that the roller E will press lubricant from the upper portion of the belt D and cause such lubricant to spread over and thoroughly lubricate the bearing of the shaft in the Babbitt metal sections J and K. Such of the lubricant as finds its way outward beyond the Babbitt metal sections J and K will be taken from the shaft A by the retainers H and caused to pass to the bottom portions f of the lower casing section a. The said excess lubricant will pass down the said in-- and the fact that it is well adapted to withstand the usage to which journal boxes are ordinariiy subjected.

The construction herein illustrated and described constitutes the preferred embodiment of my invention, but it is obvious that in practice such changes and modifications may be made as fairly fall within the scope of my invention as defined in the claims appended.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. A journal be; arranged to receive a shaft or the like and comprising a casing having a lubricant reservoir at an intermediate point of its length and bottom portions arranged at opposite sides of said reservoir and inclined downward to the -same, means for 'conven'ng lubricant from the reservoir to the shaft, means for taking excess lubricant from the shaft and causing the same to pass to the inclined bottom portions of the casing, and lubricant filters extending across the in clined bottom portions of the casing at 0pposite sides of the lubricant reservoir.
